Help!

Hello everyone,

Could you please help me?I am currently working with HAProxy in a Docker Compose setup. Here is a snippet of my configuration:

services:
  haproxy:
    image: haproxy:2.8
    container_name: haproxy
    ports:
      - 80:80
      - 443:443
    expose:
      - '80'
      - '443'
    volumes:
      - ./config/haproxy/haproxy.cfg:/usr/local/etc/haproxy/haproxy.cfg
      - ./config/haproxy/certs/:/usr/local/etc/haproxy/certs/
      - ../log:/var/log
    depends_on:
      - apache-php56
      - apache-php74
      - apache-php82
    networks:
      network:
        ipv4_address: 10.10.0.2

  apache-php56:
    user: root
    container_name: php56
    image: apache-php56
    depends_on:
      - mariadb
    volumes:
      - ./config/php56/sites-custom:/etc/apache2/sites-custom
      - ./config/php56/sites-enabled:/etc/apache2/sites-enabled
      - ./config/php56/hosts:/etc/hosts
      - ../sites:/var/www/sites
      - ../data:/data
      - ../log:/var/log
    networks:
      network:
        ipv4_address: 10.10.0.3

In the HAProxy configuration file, I have set up the following rules:

acl is_apispfr hdr(host) -i api-dev.fr
use_backend php56_backend if is_apispfr

backend php56_backend
    server apache-php56 apache-php56:80

This works perfectly.I currently have another Docker Compose setup:

services:

    volumes:

    networks:
      pap_dev_network:
        ipv4_address: 10.10.0.12
    ports:
      # HTTP
      - target: 80
        published: ${HTTP_PORT:-85}
        protocol: tcp
      # HTTPS
      - target: 443
        published: ${HTTPS_PORT:-450}
        protocol: tcp

  pap_dev_network:
    external: true

volumes:

  caddy_config:

When I use https://api-gateway.localhost:450, everything works correctly, and I can access Caddy.My question is how can I configure HAProxy to redirect https://api-gateway.localhost to https://api-gateway.localhost:450, so that HAProxy forwards the requests to the appropriate service?Thank you for your assistance!
